Heavy pollution has blown into South Korea, which is causing acid snow to fall in Seoul.

The Chosun Ilbo reports that, "Korea was blanketed by acid snow on Monday, with pH dropping to 4.2 on average in Seoul in the morning. Toxic smog compounded the problem as the concentration of fine particles soared to 112㎍/㎥, way above the safe standard of 100㎍/㎥."

The snow in Seoul is measured to have more acidity than orange juice with pulp.

As reported by the Chosun Ilbo, "The Seoul Research Institute of Public Health and Environment measured the acidity of snow at eight observation spots in the capital between 2 a.m. and 8 a.m. In the afternoon, the acidity level slightly improved to 4.3-4.4 as snow washed pollutants from the city."
